the ground.- I This mechanism may be applied in many In the operation of this invention, the hopper is filled or partially filled with dry sand, and this sand is kept very dry by means of the warm jacket, therefore there is not likely to be any clogging through dampness.

The operator of the vehicle presses the pedal and this draws the plate under the ball contact 32 whereby the electrical connection is established to the fan motor. 4

The fan is thus suitably driven and the dry sand passing ittherethrough to the outlet where it is divided and continues in its passage through to the wide mouthed nozzles, which spread it in front of the wheelsso as to enable the tires to get a proper grip of different ways to be driven as a superior machine for sandingsidewalks and such places, but the main useof it is on a motor car, in order that it will prove certainly in many instances awgood substitute for chains.

What I claim is In a sander, a hopper having an outlet passage, a closure spring-held in said outlet passage, a deflecting member dividing the sand from said outlet, tubes directing the sand from said divider to the front of the vehicle wheels, splaying nozzles at the ends of said tubes, a blower motor driven and secured below said closure, a rod operated by a suitable lever and operating said closure and electrical meansactuated by said closure for starting said motor immediately preceding the running of the sand.
